The conflict known as the assault on Arkania transpired during the Yuuzhan Vong War in the year 27 ABY, and involved the Wild Knights endeavoring to seize a Yuuzhan Vong yammosk for research purposes, as well as to thwart the Yuuzhan Vong's scheme to invade Arkania. Tsavong Lah, having conferred with Vaecta and Vergere, put to death the commanding officers who had allowed the Jedi to flee. Subsequently, he initiated a perfunctory assault on Arkania before retreating, a maneuver intended to placate Yun-Yammka.
Arkania ultimately fell under Yuuzhan Vong control in the aftermath of this engagement.
